subject ofthis application relates more par .ticularly to urethroscopes or analogous tnbular instruments adapted to' be inserted into the urethra or other channels, said instrument beingl provided at its'lower or clistal end with means for temporarily dilating' the urethral or other passage, and as employed by physicians for the 4purpose of making visual examinations as Well as treating the urethral channel or its'oavities and to'facilitate the use of other instrameints-in the urethral passage or other` channe s. l f

There' are still disadvantages or tions to instruments or, nrethroscopes of the character fabove referred to; that is to say, they support a front eover to close the outer endlof the central 'tubes passage in the act of irrigating anda fiat-flange with a gutter to collect. the' Waste-liquid iiowing back he tween the outer tube :and Wall of the pas sage during the irrigation, the result beine; achevek only closed the bore of the centrati tubawithout controllihg the act of irrigatving, as the waste liquid has free egress between the outer tube and passage and out throughI the gutter. The benefit of controlling .the act ofiirrigating as Well as otherl operations, is lost and the discomfort of the patient,by forcing thelliquidto flow among the inter-spacesof the dilating ele-- mentsof-the instrument against the Walls of the channel is increased, the act of dilating atthe distal end of the dilators causing the retraction of tissues back of the coneshaped cavity', tightening upon the tube proper andpreventingthe reflowing of the liquid. The tibe` containing' the electric .Wireiintheri'nner tube obstructs the free use ofthe auxiliary telescope and other inf struments and is insanitary. The electl lampbulb being naked isvery objectionL september v12, 191i, rt/e1* end the telescope is liable to catch on the i* ner end of the tube and prevent the insertion of the telescope and linally the`locat-ion oi the short arms on the Adilater arms forms a clogxed area at their sides which is objectionae e on account of examinations and cti er .perations construction ol the said urethroscope whereby a more simple and comparatively less expensive self-'contained instrument or "etln'osccpe is produced and in which the activant-ages or objections above referred e wholly eliminated.

tionary outer tube 9., the non-revoluble but longitudinally inerable inner` tube 10., a pluv rality ot swinging, laterally movable dilater arms 11. 11. `iointed to theinner end el the outer tube, an operating member 12., a removable telescope member 13. on the head end and an electric light bulb 14. on one et' the dilater arms. All of the abovel named elements, so tar as possible may be made'ei' Gerinan silver or other suitable material.

The diameter and length of the outer tube 9. may be of anyv suitable dimensions, such for example-as will permit the instrument to be readily inserted inte the urethral passage. The end portion el' 'the outer tube which may be termed the outer or head end is provided with a slight-ly enlarged cylindrical head 15. havinginternal serew-threads 1G., a short internal longitudinal groove 17., right angle tubular boss 18. having an inlet duct 19. and a right angle tubular boss 20. Ater the electric light wire. A groeve 21. extends longity -linally on the inside of the outer tube 9. lirom the boss 20. te the inner end oit thel tube, for the electric light wire. ln the outer tube 9. adjacent its infer end is formed a plurality of small rectangular shaped openings 22. 22., the end of the tube at the openings forming' a hinge pivot 23., one for each of the dilate arms 11. 11.

The inner tube 10. has an externally screwthreaded head end 24., a bearing ring 25., a spline 2G. which enters the groove 17. in the head and while allowing longitudinal movement of the inner tuhe prevents the inner tube from turning on its axis; and elongated inlet opening 27. in the side underthe inlet duct 19., a series of depressions 2S. 28., and a series el" small rectangular shaped openings 29. 29. -on a central longitudinal line with the openings 22. 22. in the outer tube 9. one for each oi the dilater arms 11. 11.

To the inner end. of the outer tube 9. are hinged tour circumterentially spaced elongated tapering dilater arms 11. 11.*which when closed :torni a cone-shape inner end on the instrument, as shown in F ig. 1.; each dilater 11. being concave convex in cross section. The tree or apex end of each dilater is slightly enlarged, the shape being such that when the said apex ends are in actual engagement with each other a. narrow, longitudinal space is formed between the cent edges oit' each pair of dilater arms. A hook shaped tongue 30, and an inwardly extending finger 31. are formed on the tube end et each dilater arm in a position for the hoek shaped tongue 30. to curve under and` partly around the hinge pivot 23. and enter the opening in the outer tube 9., thereby hingingthe dilater 'te the tube and for the finger 31. toenter van'opening 2,9. 29. in the inner tube 10. thereby operatively connecting the dilater arms with the inner tube, as

`The operating member 12. is in the form of ani externally screw-threaded Ysleeve in screw-thread engagement with the internal screw-threads 1G. in the headl. and havi ing a ltnurled flange 32. T he operating member 12. is rotatably secured to the head end oi' the inner tube 10. by the bearing ring 25. and a screw-threaded collar 33. as shown in Fig. 2. l

The telescope member 1 3. is in the form of a tube having a sliding fit in the bore of the inner tube 10., a slightly enlarged head portion adapted to screw over the screwthreaded end 24. of the inner tube 10. a still further enlarged end portion 36. carrying a magnifying lens 37., an outlet pipe 38. leading at right angles from the tube 34. said pipe 38. having an externally screw-threaded end 39. as shown in Fig. 2.

-An internally screw'threaded cap 40.

shown in Fig. S. adapted to screw over the end of Iand close the open end of the outlet pipe 38. which may be of any length desired. A rubber inlet tube 41. leading from a source of fluid supply, not shown, is secured te the inlet pipe 18. and a rubber outlettube 42. when used, is secured to the outlet pipe 38. and extends downward to a receiving recap# tacle, not shown.

`The electric light bulb 14. is entirely and permanently inclosed in a metal casing 43. having an opening or window 44. through which the light shines and a loclting'firojec` tion 45. One et' the light terminals is attached to the metal casing 43. and the other terminal at the Contact point 4G. A lamp clip 47. having a longitudinal slot 48. is secured longitudinally to the inside of one ot" the dilater arms 11. and the lamp is detachably secured to the dilater arm by inserting or pushing the lamp through the clip 47. and then turning the lamp so as te brinfr the projection 45. against the innerA end o. the clip, as shown in Figs. 2. and 5. A tube 49. is secured to or may be embedded in the iii-- nel` face of the dilater arm 11. An insulated, Wire 50. is secured in the tube 49., one end 51. of the bare wire beingI bent into Contact with the contact point 4o. on the electric light bulb 14. and the other end of the bare wire terminating in the end 52. at the hinge joint of the dilater arm. An insulated wire F53. extends inward from a battery, not shown, through the boss 20. and the longitudinal roeve 21. `and'terminates in the bare end 54.

he bare ends 52.. and .54. f forni contact points which come into contact and close the circuit when the dilater arms are opened.- A Wire 55. extends` from Vthe battery, not

shown, to a. binding postn. on the head 15. the metal from the binding post 56. to the clip 47. forming one half of `the electric` light circuit.

By means of this improved the unobstructed insertion 0f Aa telescopeior instrument is readily permitted. The urethroscope when inserted, as in use, may be easily and quickly manipulated 'so as to accurately and positively operate the dilator arms simultaneously to the sired extent. thereby correspondingly enlarging thatportion ct' the urethral passage and temporarily producing a complete dilation of the folds ci the cavity, preparatory to examinations, iorceps operation, irrigation or other operations.. A

ln the use of my improved urethroscope the instrument lirst lsterilized is inserted into the urethral passage or other channels to the desired extent followed by turning the operating member 12. to the right thereby "respondingly moving the inner tube 10.

' vthvvise inward When the edges ot the i,.rings 29. 29. of the inner tube engaging with the fingers 31. 31. on the dilater arms 11. 11. thereby opening the dilator arms, bringing the ends 52. and .54. of'the Wires fan'd 53. into contact, closing the circuit I and energizing or lighting the lamp 14. A

further turning of the operating member to. the right still further opens the dilator arms 11. 11. The physician may then make a. visual examination or inspection of the thus acted upon parts.

W hen irrigating, the remedial liquid flows through the tube 4 1. the inlet duct 19. the opening 27. vthrough the bore of the inner tube 10. to the enlarged portion of the urethra, then flowing back through the bore of the inner tube, as in the case ot a retrojector vand escaping out through the outlet- Apipe '38. The remedial liquid is thus kept entirely out of contact With the external portions of the human body. At the completion of thc operations the act of turning the operating member 12. to the leftretracts the inner tube 10. and the dilater arms 11. 11. back to their normal positions and simultaneously breaking the contact of the Wire ends 52. and 54. openingy the circuit and cutting out` the electric lamp 14. The instrument is then removed from .the urethra.

or other channel. lThe telescope member 13. may be easily removed by unseren/ing the same from the end of the inner tube 10. for the insertion ofother instruments into the ureth'roscope.
